(NaturalNews) In our industrialized society, we have lost natural twilight, the time of night when the moon rises and we move indoors to sleep. Twilight is when work is done and the body prepares for sleep. With indoor lighting, the natural stimulus that leads to sleep is disturbed. One of the most prevalent causes of insomnia and other sleep disturbances is the addition of light past the time of twilight. This so-called light pollution has been blamed for much illness, especially the loss of the natural sleep cycles. Viewed from space, out globe is illuminated around the clock, especially in the urbanized nations and continents, such as the United States and Europe. (See link at bottom of page for a website that shows this map.) Changing the way we light our homes at night can recreate an indoor twilight, and improve sleep.
